The DEEP DRILLER is loaded as shown in the Sample Load Form #2 (Ballasting to Survival). What is the metacentric height corrected for transverse free surface effects if 100.76 long tons of ballast are added to Ballast Tank #8S to replace the discharge of all bulk materials?

Correct Answer: Option D — 12.13 feet

Adding ballast while discharging bulk loads alters displacement and free surface moments. Incorporating the added ballast weight and tank free surface corrections into the transverse metacentric height formula results in a corrected GM of 12.13 feet.
